12 Read Device Registers (big Endian)

Description

This block is identical to block 0x10, except that the address, word count, and data are

returned in big-Endian, or network, byte order. Notice that the Length field is still in

little-Endian byte order.

Request

The request uses this format:

12 Address WordCnt00

0A 00

00 SeqNumVer

Address

The register address to begin reading from.

WordCnt

The number of registers to read (1-2048 in TCP, 1-512 in UDP).

Response

The success response follows this format:

WC*2+6 92 00 Data

Data

n-1

00 SeqNumVer

Data

-Data

n-1

The data read from the address requested.

Example

The Command Position, Target Position, Actual Position, Counts, and Status Word for

axis 1 are located at register addresses 10-14. If a user wants to read these five registers,

the following packet would be sent to the RMC:

12 000A 00 0A 00 050000 12 3302

If these fields have the values 4000 (0x0FA0), 4000 (0x0FA0), 4001 (0x0FA1), 4247

(0x1097), and 0x0043, the response would be the following:

92 0010 00 0F A0 0F A0 0F A1

10 97 00 43

00 12 3302
